Description

For running the method for gear arrangement of motor vehicles and corresponding gear arrangement
Technical field
The present invention relates to a kind of method of the gear arrangement for running motor vehicles, wherein, this gear arrangement includes Automatically clutch and manual variator.The invention still further relates to a kind of gear arrangement.
Background technology
Gear arrangement is preferred for inside the power assembly system of motor vehicles transmitting torque.This gear arrangement is for example It is arranged between the power set of motor vehicles and at least one powered vehicle bridge of motor vehicles.This power set has at least one Individual drive train, such as internal combustion engine or motor.This power set may be designed in mixed power plant and has at least two Drive train, this two drive train are preferably different each other.Internal combustion engine is set for example in the range of mixed power plant And motor is as driving means.
Gear arrangement includes automatic clutch and manual variator.This clutch here especially sets up power set Effect and variator between connects, and this clutch is connected on the input shaft of variator or is connected with the effect of this input shaft, especially It is rigidly and/or constantly.The output shaft of variator is preferably connected with least one powered vehicle bridge effect of motor vehicles, Especially equally rigidly and/or for good and all connect.That is, the rotating speed of output shaft depends directly on the traveling speed of motor vehicles Degree, vice versa.
The effect that clutch is used for especially alternatively setting up or interrupting between power set and variator connects. In the clutch at least in part, being especially fully engaged with, the torque being provided by power set is delivered on variator.Instead It, if clutch is detached, is especially completely separate, act on disconnecting.Therefore there is no torque from power set It is delivered to gear arrangement, vice versa.This clutch designs is automatic clutch, that is, adjusts dress by means of automatic Put this clutch of actuating.That is, for this clutch dispensing actuator, especially electric actuator, this actuator is to clutch Activated.
Actuator and and then controling of clutch for example depend on clutch pedal position and/or depend in controller Predetermined value is realized.This clutch can not only by motor vehicles driver by means of clutch pedal but also can be by motor-driven The controller of car or power set controls.This clutch only electricity ground, couple with clutch pedal on-mechanical.Can also arrange and appoint The clutch operating element of meaning replaces clutch pedal.Transmission design is manual transmission.Distribute behaviour for this manual transmission Make element, such as gear level, the driver of motor vehicles can activate variator by this gear level, for example, can arrange desired Gear.
Content of the invention
Therefore the purpose of the present invention is, proposes a kind of method for running gear arrangement, the method is with respect to known Method have the advantage that it is particularly possible to more reliably operate gear arrangement.
According to the present invention, the method that above-mentioned purpose passes through the feature of claim 1 is realized.Herein propose, in variator dress In at least one method of operation put, if recognize the actuating of variator when clutch is at least partially separate, it is being linked into Clutch is made to engage before gear on variator.This at least one method of operation be preferably the method for operation so, wherein from Clutch is at least partially separated, is especially kept completely separate.Here, gear can be arranged on variator, especially forward gear or fall Car bumper.But neutral or neutral gear position can also be set.Multiple forward range and one reversing gear, especially just what a Reversing gear preferably comprises the gear of variator.
In the normal operating mode of gear arrangement, wherein it is used for driving motor vehicles by the torque that power set produce, Make clutch separation in order to realize shift transformation, be subsequently linked into desired gear, so that clutch is engaged, so that Between at least one powered vehicle bridge of power set and motor vehicles, foundation effect connects.If hung on variator Enter gear, this gear does not simultaneously meet desired gear, then remove previous gear first after making clutch separation, then just hang Enter desired gear.Next clutch is made to engage as described.
In contrast, under given conditions, clutch is engaged before being linked into gear.Can also arrange, identical Under conditions of, before being linked into gear, i.e. so that clutch is engaged before in fact activating variator.
If recognize the actuating of variator when clutch is at least partially separate, clutch is being linked into and/or is removing gear Should be engaged before position.As described above, can be designed as making clutch consistently separate as far as possible in this method of operation. That preferably realizes motor vehicles in this method of operation slides (Segeln), thus this method of operation is as sliding the method for operation. As stated in the beginning, the rotating speed of the output shaft of variator depends on the travel speed of current motor vehicles.Because working as clutch at least When being partially separated, especially when the clutch is fully disengaged, the actuating of variator is removed or is linked into gear and only will The power asking little expends, then may lead to variator is unexpectedly activated, such as when automobile driver encounters gear level.This Actuating can also be intentionally, for example inadequately activate gear level.
If being linked into gear, the output shaft of the variator input shaft by speed ratio corresponding with gear and variator Effect connects.Correspondingly input shaft is taken to following rotating speed, this rotating speed is determined by the rotating speed of output shaft and the speed ratio of gear.If Speed ratio is too high, then the rotating speed of input shaft is very high.In extreme circumstances, the rotating speed of input shaft is more than maximum license rotating speed.This In the case of, may lead to damage, for example, lead to act on the fracture of the clutch disc being connected with input shaft.
In order to prevent this situation, once recognizing the actuating of variator, just at least in part, be especially fully engaged with from Clutch.If clutch engages at least in part, the actuating of variator is removed or is linked into gear and significantly becomes difficult, Especially because undercut/the undercutting (Hinterschneidung) of clutch engagement tooth.Therefore prevent in the above described manner or at least Make driver or by mistake activate variator change hardly possible particularly by gear level otherwise.
Another design of the present invention proposes, activates and refer to remove or be linked into the gear of variator.Below Describe this mode.Especially advantageously prevent and remove gear, however must at least make gear be linked into interruption.For example feasible , do not allow in principle to be linked into each gear.But can also optionally not allow to be linked into only at least one gear, for example This is because this gear has too high speed ratio.
Another improvement project of the present invention proposes, and so that clutch is engaged when recognizing and being linked into gear, this gear has Speed ratio more than slowest ratio.Have also shown that this situation.Especially should prevent variator input shaft excessive Rotating speed, for example exceedes maximum input shaft rotating speed.
Another preferred design of the present invention proposes, and slowest ratio is by the output rotating speed of variator and maximum input shaft Rotating speed determines.As discussed, output rotating speed directly depends on the travel speed of motor vehicles, this is because the output shaft of variator is excellent Choosing rigidly and/or constantly with least one powered vehicle bridge effect of motor vehicles is connected.Maximum input shaft rotating speed is same It is known, this maximum input shaft rotating speed is the maximum (top) speed of the permission of input shaft.Obtain slowest ratio by this two parameters, The gear being linked into does not allow more than this slowest ratio, so that the rotating speed following the input shaft for variator limits.
Can additionally or alternatively propose, only when exporting rotating speed more than limiting speed, implement the joint of clutch. In the case that the travel speed of motor vehicles is little, clutch should not made to engage, this is because input shaft is not in super wherein Cross the rotating speed of maximum input shaft rotating speed.When export rotating speed be less than limit speed when, then especially do not import/start described at least one The individual method of operation.Only when output rotating speed exceedes restriction speed, then implement the corresponding method of operation.
Another design of the present invention proposes, and application slides the method for operation as the method for operation.Slide operation side at this In formula, do not use or do not need power set to be used for driving motor vehicles.This can be for example following situation, i.e. external action, example As gravity impact is sufficiently used for ensureing the desired travel speed of motor vehicles.This especially following situation, is disposed with motor-driven thereon The gradient on the ground of car exceedes the gradient of determination, wherein motor vehicles in travel direction downward-sloping and and then downward slope direction refer to To.In sliding the method for operation, so control automatic clutch, so that clutch is then separated, be especially kept completely separate.Additionally, Power set can also be closed or at least power set are run in free-runing operation mode, this power dress in this free-runing operation mode Put and only run with idler revolutions.
Another preferred form of implementation of the present invention proposes, makes clutch separation when importing/bringing into operation mode. This especially following situation, that is, be used and slide the method for operation as the method for operation.That is, for example led by the controller of motor vehicles Enter and slide the method for operation, make clutch separation after wherein simultaneously or at least and then importing the method for operation, be especially kept completely separate.
Another preferred design of the present invention proposes, makes clutch after the time period determining after splicing Separate again.This is preferably following situation, if setting slides the method for operation as the method for operation.This clutch is preferably only Engage during the time period determining.This time period here for example so measures, and stops the actuating to variator in this time period, Especially stop and remove or be linked into gear.In order to realize gently engaging and/or separate, the time period here of determination can be according to machine The rotating speed of the travel speed of motor-car or input shaft determines.Situation in larger travel speed or the larger rotating speed of input shaft Under, therefore can select the longer time period compared with the situation of less travel speed or relatively low rotating speed.
Finally can arrange, be used for the actuating to variator for the identification using neutral gear sensor or full shift sensor.If For example it is particularly the case herein includes automatic clutch and manual variator, then this biography for gear arrangement Sensor preferably there is originally.This neutral gear sensor especially identifies, variator or gear level are arranged in neutral or idle running gear. And shift sensor identification is linked into and/or removes the situation of special gear entirely.
Normally only be can determine that using neutral gear sensor and remove or be linked into gear, and full shift sensor may also provide as follows Information, is carried out for which gear.Preferably so configured neutral gear sensor and full shift sensor, identify from the beginning Put into gear or pluck gear, wherein in fact also do not remove in this moment or be linked into this gear.It is arranged so as to and configure neutral Sensor and full shift sensor, that is, this sensor recognize the actuating to variator in time, such that it is able to by clutch Joint prevents from actually removing gear or is at least actually linked into gear.
The present invention also designs a kind of gear arrangement for motor vehicles, is particularly useful for implementing according to above-mentioned form of implementation Method, wherein gear arrangement include automatic clutch and manual variator.Herein propose, gear arrangement designs for this For at least one method of operation of this gear arrangement, when recognizing to speed change when clutch is at least partially separated The actuating of device, made clutch engage before being linked into gear.It has been noted that this method of operation or this gear arrangement The advantage of design.Methods described and described gear arrangement can improve further according to above-mentioned form of implementation, thus All referring to described embodiment.
